Abstract
The utility model discloses a dust monitor, including the box, the top of box is equipped with the handle, and the front of box is equipped with liquid crystal display, and the side of box is equipped with power source, still is equipped with detection window in the front of box to locate to be equipped with the detection membrane at detection window, detect the membrane lock joint and on detection window, detect sealing connection between membrane and the detection window, the outside of detecting the membrane is equipped with filtration membrane. Dust monitor, can be convenient for detect the dismantlement and the installation of membrane to the filtration membrane in its outside can change at any time, guarantees the degree of accuracy that detects, and when need not using, the glass piece on the braced frame of the accessible outside shelters from detection window.
Description
Technical field
This utility model is a kind of dust monitoring instrument, belongs to fuel gas and dust monitoring device field.
Background technology
Dust monitoring instrument is used for the place such as mine, construction, can accurately and timely reflect and connect the respirable dust that dirt personnel suck
The pollution situation of dust in quality and different dusts Work places, the sanitary condition for accurate evaluating operation place provides reliable number
According to, it is adaptable to underground coal mine and other contain the Work places of explosion hazard gas.
Owing to the feature of dust monitoring instrument itself determines, it is during carrying out gas, particulate matter detection, if can not be right
Some of which bulky grain thing filters, and testing result is also brought along deviation.
And owing to detecting the severe of environment, the service life of its sensor is the most comparatively short, so being also accomplished by often changing,
Changing is a more complicated thing for dust monitoring instrument, and relates to the biography in Renewal process and after replacing
The problem of sensor sealing.This utility model is based on this problem, it is provided that a kind of dust monitoring instrument that can be conveniently replaceable sensor.
Utility model content
The purpose of this utility model is to provide a kind of dust monitoring instrument, and it is provided with removable sensor installing structure, solves biography
The problem that sensor is changed.
The purpose of this utility model implements by the following technical programs:
A kind of dust monitoring instrument, including casing, the top of casing is provided with handle, and the front of casing is provided with LCDs, casing
Side be provided with power interface, be additionally provided with detection window in the front of casing, and at detection window, be provided with detection membrane, described
Detection membrane snaps onto on detection window, is tightly connected between detection membrane and detection window；It is provided with filtration in the outside of described detection membrane
Film.
Being provided with fixed mount around described detection window on the casing outside described detection window, described fixed mount is sealedly connected on institute
Stating on casing, described filter membrane is connected on fixed mount by the way of grafting.
Being provided with inserting groove on described fixed mount, described filter membrane is plugged on described inserting groove.
Described inserting groove is located at the top of described fixed mount.
Being provided with support frame in the outside of described fixed mount, in described support frame, embedded connection has sheet glass, described glass
Sheet covers described detection window.
Dust monitoring instrument described in the utility model, it is possible to be easy to dismounting and the installation of described detection membrane, and the filtration outside it
Film can be replaced at any time, it is ensured that the accuracy of detection；And need not use when, can be by outside-supporting framework
Sheet glass detection window is blocked.
